Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as f(x) where x is the input.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What does j(-1) represent in the function j(x) = 2x + 3?

Back

j(-1) represents the output of the function when the input x is -1. It is calculated as j(-1) = 2(-1) + 3 = 1.

Front

What is the y-intercept of the equation 4x + 2y = -12?

Back

The y-intercept is found by setting x = 0. The equation becomes 2y = -12, so y = -6.

Front

How do you evaluate a function at a specific point, such as f(1)?

Back

To evaluate f(1), substitute 1 for x in the function's expression and simplify.

Front

What is the output of h(x) = 5 - 9x when x = 8?

Back

h(8) = 5 - 9(8) = 5 - 72 = -67.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the difference between independent and dependent variables in a function?

Back

The independent variable is the input (x), while the dependent variable is the output (y) that depends on the input.
